Re Routing Puns

So we've been driving for about 30 minutes down state route 1 and talking has died down a bit. We're just listening to some oldies on the radio when my dad says, "Flo Rida must be pretty popular down here. I keep seeing his name everywhere." I replied, "really? I haven't seen it anywhere..... Ugh Shut up dad."

Edit: Key West is the most southern part of the state of Florida, USA. Flo Rida is a rapper. Flo Rida is really popular in Florida. My dad saw Flo Rida a lot during our drive in Florida. If you don't get it yet, leave /r/dadjokes

Edit 2 because people keep struggling. If this doesn't help you understand the joke you're lost.
